(Cl. 153-21) The present inventiongenerally relates to a metal forming apparatus and, in particular, isdirected to an improved machine for joggling or offsetting structuralshapes such as bars of various cross-sectional configuration.

In the use of structural shapes to reinforce sheet memn bers or skin asis frequently encountered in the manufacture of buses, railroad cars,and aircraft, it is frequently desirable to form lap joints whichprovide a continuous surface for supporting the sheet to which it issecured. In order to do this, the portion of one of the members formingthe lap is oifset or jogged an amount equal to the gauge or thickness ofthe mating member so that when the joint is formed, the outer supportingsurfaces of the structural members are co-planar, thus providing acontinuous supporting surface for the contiguous skin.

Joggling of this type is commonly performed with steel dies in brakes orpresses since the power requirements for the operation usually precludethe use of manualf tools. Due to the complexity of the structure ofaircraft and the like, a wide variety of structural reinforcing shapesof many different gauges are conventionally ernployed. As a result, itis usually necessary to provide ya proportionately high number ofjoggling dies forming an appreciable portion of the tooling cost.Additionally, the time required for setting up the dies in the pressesor brakes is considerable, especially when only relatively short runsare required.

The principal objective of the present invention is to provide aunitary, compact, and highly flexible apparatus for joggling oroffsetting, employing relatively inexpensive tools. The apparatus of thepresent invention fundamentally dilers from conventional practice inutilizing two pairs of jaws conforming to the section to be offset andadapted to be clamped contiguously at the point where the desired oifsetis required, having power means for moving the pairs of jaws relative toeach other to stretch the work piece in the desired direction to formthe joggle. This is in distinction to forming the joggle between hardsteel dies as previously described which quite frequently embrittles andcracks the workpiece in the forming area, particularly in the use of24ST and 75ST aluminum and magnesium.

A further object of the invention is to provide ap-` paratus of the typeunder consideration wherein the oifsetting of the workpiece is obtainedby stretching the material, whether metallic or non-metallic, whilesupported on either side of the joggle between pairs of relativelyinexpensive jaws. Since the jaws of the machine are not subject to highimpact or press loads for forming, they may be economically fabricatedfrom castable material, utilizing a section of the desired workpiece asa pattern.

Still a further object of the invention is to provide a joggling machinecomprising a iirst stationary structure for supporting a pair ofclamping jaws, a secondrelatively movable structure supporting a secondpair of clamping jaws and power means for selectively moving ICC thesecond structure with respect to the rst in a plurality of directions.

A further object of the invention is to provide a machine as describedin which the limits and direction of motion of the power actuating meansremains the same while the direction of relative motion between themovable and stationary structures can be selectively changed or modifiedby means of a novel and simple cam mechamsm.

Another objective of the invention is to provide a joggling machinewhich, while susceptible of motor actuation, can be convenientlyoperated by simple manual means.

Still another feature and objective of the present invention resides inthe provision of a joggling machine of the above general descriptionwherein all of the operating controls and adjustments are located insuch a manner as to be easily accessible without the necessity forchanging the operators position during the operation of the machine.

Other features and objectives of the present invention will be apparentfrom the following description in conjunction with the accompanyingdrawings in which like figures of reference denote like parts throughoutthe several views.

The joggling machine shown in the attached drawings and hereafterdescribed constitutes a preferred embodi-4 ment ot the invention. Itwill be apparent that the apparatus may be modied in many detailedrespects witht 4out departing from the principles of the invention whichjoggling members formed of other types of material.

Referring particularly to Fig. l, the juggling apparatus p of thepresent invention consists essentially of a pedestal 1 adapted for flooror bench mounting, and a relatively movable assembly 2 supported fromthe pedestal 1 in such a manner that the former may be moved betweenarsenite.

preselected limits with respect to the pedestal 1 in response tomovement of a lever 3. motion between the two elements 1 and 2 is, atall times, accomplished by movement of the lever arm 3 between the upperand lower positions indicated in full and broken lines in Fig. 1, thedirection of relative motion may be pre-selected by manual rotation of acontrol wheel 4 disposed on an outer surface of the movable assembly 2.For example, with the control wheel 4 positioned as shown with anindicating indicia 4a pointing towards the rear of the machine,depression of the lever 3 to its lower position will cause the movableassembly 2 to move from a neutral position with respect to the pedestal1, horizontally and to the rear as indicated by broken lines. Similarly,by setting the control wheel 4 in the appropriately indicated position,the same depressing movement of the lever 3 will cause the movableassembly 2 to be moved in a plurality of directions with respect to theassembly 1 including upwards, downwards, or towards the front ofthemachine.

The purpose of the apparatus contemplated in the present invention istojoggle or olfset structural shapes such as bars, angles, or elementsof U, V, or Z sections. A portion of a typical workpiece A is shown inFig. la as illustrative of the general form of work for which theapparatus of the present invention is adapted. The workpiece A shown, isof generally Z-shaped section comprising a pair of spaced verticalflanges a1 joined at their inner edges by a horizontal web portion a2.Indicating the operation which the present apparatus is adapted toperform, the workpiece A has an offset or joggle a3 in such a form thatwhen the joggled portion of A is mated with the end of a piece ofmaterial of the same shape to form a lap joint, the outer faces of theadjoining flanges a1 are co-planar, presenting a vcontinuous surfaceadaptable for attachment to a skin or sheet without discontinuity.

The apparatus of the present invention produces joggles or offsets ofthe character indicated at a3 in connection with the workpiece A, byrigidly clamping or holding the workpiece A between the pedestal 1 andthe movable assembly 2 with the portion to be joggled located at theirmating surfaces, and then displacing the movable assem- `bly 2 withrespect to the pedestal 1 in the direction of the desired joggle, byoperation of the lever 3.

The pedestal 1 comprises essentially a base plate 10, a pair ofvertically disposed side plates 11 and 12, anda horizontal table plate14. The side plate 11 is tiat and relatively thick and detines acontinuous outer working surface 15. The side plate 12 comprises a fiatcentral portion 16 spaced from plate 11 having rounded portions 17 whoseedges are adapted to abut against and be` fastened as by welding to theinner surface of the side plate 11 defining a central cavity 19 Withinthe pedestal 1. The horizontal base plate is secured as by welding tothe lower edges of the side plates 11 and 12y and may be providedl withsuitable mounting holes 21 for bolting the pedestal 1 to a oor or bench,The table plate 14 is generally rectangular having an upper workingsurface 22 and is welded or otherwise secured to the upper edges of theside plates 11 and 12 with its inner edge 23 contiguous with the workingsurface of the side plate 11v and with the working surface 22 disposedat a 90 angle thereto.

The movable assembly 2 comprises a hat rectangular back plate 24 havingan outer working surface 25, a table plate 26, having a working surface31, a threesidedwall member 27, and a cover plate 28. The back plate 24of the assembly 2 conforms generally in Width tothe side plate 11 of thepedestal l..

The rectangular table plate 26 is secured as by Welding with an inneredge 29 abutting and aligned withthe upper edge of the back plate 24 andso that its upper working surface 31 is normal thereto. The wall mem-While the relative-V ber 27, asbest shown in Figure 2, is U-shapedhavinga 7 pair of vertical side elements 32 and 33 joined by a centralportion 34 and is adapted to be secured by Welding at the upper edges ofthe wall portions 32 and 33 to the lower face of the table plate 26 andthe lateral edges of the entire wall member 27 to the inner face of theback plate 24 to form a generally box-like enclosure. The cover plate 28conforms to the wall member 27 and is adapted to be movably bolted tothe outer edge thereof.

In assembly, the movable assembly 2 is supported on the pedestal 1, insuch a manner that in the machines vertical position the working surface25 of plate 24 of the former is opposed to and slightly spaced from theworking surface 15 of the pedestal 1, and the upper surfaces 22 and 31of the table plates 14 and 26 respectively are coplanar. The assembly 2is supported upon side plate 11 of pedestal 1 by a series of supportassemblies 35, four being shown. A support assembly 35 is disposedadjacent each corner of the back plate 24 within thebox-like enclosureformed by the table plate 26 and the wall member 27. Each of the supportassemblies 35, as best illustrated in Figures 3 and l0, is secured tothe sideV plate 11 of the pedestal 1 by means of a central stud 36having a cylindrical shaft portion 37, a head 38 and terminating in anundercut threaded portion 39. The studs 36 are disposed with their headportions 38 within the cavity 19 of the pedestal l, extending outwardlythrough holes 4) in the side plate 11, through Washers 41, and throughaligned holes 42 in reinforcing blocks 43 which are welded to the innersurface of thc side, plate 11, in such a manner that the shaft andthreaded portions 37 and 39 extend through the back plate 24 of theassembly 2. In addition to the stud 36, each of the support assemblies35 comprises a generally cylindrical body member 44, a support block 45,a sprocket 46, a retainer plate 47, and a nut 43. The body member 44 isyundercut on its rear edge to form a bearing surface 49 which is adaptedfor rotatable support in a hole 51 in the'back plate 24 of the assembly2. The body member 44" is provided with a central counterbore 52 whichaccommodates a circular central boss 53 of the sprocket 46 and in whichthe latter is secured against rotation by a pairy of clamping bolts 54having wedging members 55 adapted to-engage the outer surface of theboss 53 on being tightened. The support block 45 is apertured to rrotate on the extended shaft portion 37 of the stud 36 and is generallysquare in cross section, fitting for sliding movement a transverse slot56 milled across the rear face'ST of the body member 44. The circularslot re- 'tainer plate 47 is centrally apcrtured to accommodate thethreaded end portion 39 of the stud 36 and is of smaller diameter thanthe teeth 58 of the sprocketl 46 but larger than the diameter of thecentral bore 59 thereof, andlserves to position the assembly 2 withrespect to thefpedestal 1, when locked by the nut 4S on the threadedportion 39 ofthe stud 36. A grease fitting 61 is centrally provided inthe end of the stud 36 communicating by a suitably drilled passage 62 tothe inner counterborc of` the body member 44 to provide lubrication.

From the foregoing description it will be apparent that when` thesupport assemblies 35 are located in positions in which the slots 56 ofthe body members 44 lie parallel to the edges of plate 24, that is, allextend in the same direction, the actionof the support blocks 45 thereinlimits the direction of freedom of the assembly 2 with respect to thepedestal 1 to the direction of parallelism of the slots 56( For example,when the slots 56 of the support assemblies 35 are horizontal as shownin Fig. 7, the assembly 2 is restricted to horizontal movement in eitherdirection from neutral, while positioning the slots 56 of the supportassemblies 35 to the vertical, as illustrated in Fig., 8, restrictsmovement of the assembly 2 to either direction vinV a vertical plane.

When the support assemblies 35 are all positioned in a1- horizonta-ldirection, the weight of the assembly 2 is transmitted-,to and,supportedv byv the pedestal 1 through,

engagement vof the lslots "56 withthe support blocks 45. When the slots56 are ina vertical position a's shown? in Fig. 8, the assembly 2 issupported against the force vof4 gravity by a spring-loaded cylinder.6?mounted on the side plate 11 of the pedestal 1, comprising a cylinderbodyy 64,` a `plunger 65, and a compression spring 66.`

The cylinder body 64` has a` central axial bore 67 Aex` tending throughone end and adapted to loosely accom-` modate the spring 66. The plunger65 ts withinthe bore 67 of the cylinderbody 64 and is adapted to besupported therein by the spring 66 and project above the open endthereof. The cylinder body 64 is provided with laterally extendingmounting `lugs 68 drilled to accommodate mounting bolts' 69.` The backplate 24 ofthe assembly 2 is relieved by openings 71 through which thebolts 69 extend into suitably tapped holes in the side plate 11 of thepedestalZ. Thecylinder 63 is supported from the side plate 11 and inspaced relation from theback t plate 24 by means ofr spacer bushingsV 72around each of the mounting bolts 69. y'The openings 71 in the backplate 24 provide su'icient clearance with ,the spacer bushings 72 topermit the desired `iimits of movement `in all directions between theassembly 2 and the pedestal` 1.

-In\assembly,` the cylinder 63 is located with the open end of thecylinder body 64 upwards and the upperface of the plunger 65 bearingagainst the lower face of the table plate 26. An adjusting screw 73 isprovidedrin an axial threaded hole through the lower closed end or' thecylinder body 64, its upper end engaging a washer 74 within the bore 67which in turn supports the lower end of the spring 66. By means of theadjusting screw 73, the compression of the spring 66 may be balancedagainst the weight of the assembly 2-fwhen the support assemblies arepositioned with the slots 46 in a vertical direction, so that the upperWorking surfaces v:il and 22 of the table plates` 26 and 14 respectivelyare coplanar, characterizing the neutral position of the presentjoggling machine.

As stated hereinabove vertical plate 24 and table plate 26 of movableassembly 2 are adapted to be moved back and forth horizontally and upand down vertically, the particular direction of movement beingdetermined by the position assumed by slot 56 of body member 44 whichconfines support block 45. The manner and means whereby the position ofslot 56 is changed will now be described. The operative means foreffecting this change of position includes control wheel 4, which asshown, comprises a generally cylindrical body member 81 to which aplurality of outwardly projecting handle bars 82 are suitably aixed.Body member 81 is counterbored as at 83 to accept a bolt 84 whichprojects through the bore to the exterior of body member 81 andisrthreaded at its outer end 35 to be received within a threaded hoie 86in plate 24 of movable assembly 2, thereby to rigidly affix bolt 84 toplate 24. Bolt 84 serves as a rotatable support for body member 81 withthe interior walls of bore 83 engaging and riding upon head 87 of bolt84 and upon the shank thereof as at 88. A spring 89 is confined withinbore 83, encircling bolt 84 and having its opposite ends seating uponhead 87 of the bolt and upon an annular shoulder 91 provided within bore83.

Disposed between the inner end of body member 81 of control handle 4 andthe front surface of plate 24 is a drive sprocket 92 having a rotatablesupport upon a bearing surface 93 provided by bolt 84. Drive sprocket 92is made to rotate in unison with body member 81 by means of a pin 94 oneof whose ends is positioned within a bore 95 which extends from the rearsurface of body member 81, pin 94 being maintained therein as by a forcefit. An opening 96 extending from the front surface 97 of body memberj81communicates with bore 95 and affords a passage by means of which asuitable tool may be inserted to drive out pin 94 when desired. Pin 94projects from body member 81 through an opening 98 aligned with bore 95to provide the interconnection between body member 81 and drive sprocket92 whereby 6 they will move in unison. A series of circular openingsI101, 102, 103, and 104 are provided in plate 24 in annularly and equallyspaced relationship about threaded hole 86 which carries bolt 84. Theprojecting'end 105 of pin 94 is adapted selectively to be passed throughany of the openings 101, 102, 103 and 104 to project into a cavity 106afforded by side plate 11 of pedestal 1.` The purpose of projecting theend of pin 94 within cavity 106 will be described hereinafter. Theselective positioning of pin 94 within the annularly arranged openingsmentioned is accomplished by pulling upon the handle hars 82 tojmovecontrol wheel 4 normally away from plate 24 against the force of spring89 to withdraw the outer end of pin 94 from the particular opening beingoccupied. Wheel 4 may then be rotated about bolt 84 to position pin 94for acceptance by any of the other of the annularly arranged openings.VUpon release of the wheel 4 compressed spring 89 will exert its forceto move body member 81 slidably upon bolt 84 toward plate 2 4 to passpin 94 through the desired opening to once again project within cavity106. It is obvious that as control wheel 4 is rotated the position of`arrow 4a is changed and made to point in the direction of movementdesired for movable assembly 2. Rotation of control wheel 4 when pin 94is in its freed position will result in a change in the direction of theslots 56. This change is effected through the agency of a drive chain107 which meshes with the teeth 58,01? the various sprockets 46 of theassemblies 35 and fits upon the teeth of drive sprocket v 92. It isreadily apparent that when body member 81 of control wheel 4 is manuallyrotated upon bolt 84 drive sprocket 92 is made to rotate with it byreason ofthe;V interconnection therewith through pin 94. Rotation offdrive sprocket 92 moves drive chain 107 to elect like rotation of thevarious sprockets 46. Sprockets 46, as

kdescribed hereinabove, are aixed tobody members -44 of assemblies 35which members 44 have the slots 56 formed in their rear faces 57.Therefore, when a turn-. mg force is applied to sprockets 46 during thetime thatpin 94 is in withdrawn .position rotation of body members 44about bolts 36V of assemblies 35 will occur to thereby change thedirection of the slots 56.V ,At this` time there isno movement of plate24, rotation of central handle 4 merely results in movement of thevarious sprockets to turn the body members `44 to align the slots 56 ina desired direction. The manner in which force is applied to effectmovement of `plate 24 and in the di@ able assemblyA 2 relative topedestal 1 is applied against the portion of pin 94 which projects intocavity 106 inl plate 11. This force is provided by a Camming wheel 111whose constructionis best shown in Figure 5a; As iilusj trated cammingwheel 111 comprises an annular body member 112 having four arcuateopenings or slots 113., 114, 115 and 116 formed about its periphery andequally .paced therearound. Slots 113, 114, 115, and 116 are adapted toalign with openings 101, 102, 103, and 104 in plate 24 and projectingportion 105 of pin 94 will extend into one or the other of these slotsdependent on which direction it is desired that movable assembly 2 bemoved. Camming wheel 111 is rigidly atiixed to reduced portion 117 of ashaft 118 which projects into cavity 106 of plate 11. Shaft 118 extendsbetween plates 11 and 12 of pedestal 1 and is rotatably supportedadjacent one end by a support member 121 axed to the inner face of plate11 as by welding. Support member 121 is located on plate 11 adjacentcavity 106 and closes one end thereof. This member 121 is centrallyapertured to accommodate a ay-rexezeeaA ous suitably drilled passagesI127 to the two bearings 122?.l

and 123.

Joggle lever 3 is affordedto eiect rotative movement of shaft 113 toactuate camming wheel 111 and thereby pin 94 and movable assembly 2.This movement will be fully explained hereinafter. J oggle lever 3 isoperatively mounted to pedestalfl, being pivotally supported, as bestshown in Figures 3 and 4, upon a stationary pin 123 which extendsthrough an opening 129, provided in lever 3spaced from its lower end andan aligned opening 131 in plate 12, and spans cavity 19 to be threadedinto plate 11. Bearing blocks 132 and 133 welded to the inner faces ofplatesll andl 12 provide support for pin 128. The motion of joggle lever3 about the pivotal support of pin 128 is transmitted as a rotationalforce to shaft 118 through a pair of link'elements 134 and 135, linkelement 134being of generally L-shape. loggie lever 3 at its lower endis bifurcated, as shown at 136 to accept the 'f lower end of linkelement 134. A pin 137 pivotally connects this end of link element 134to bifurcated portion 136. A pivotal interconnection is afforded betweenlink elements 134 and 135 by a pin 138 which connects the lower end ofthe second link element to link element 134 at a point spaced from theupper end of the latter. A locking assembly comprising a pair of studs141 and a locking bar 142 rigidly atixes the opposite end of linkelement 135 to projecting portion 125 of shaft 118.

Joggle lever 3 in being moved downwardly or counterl' clockwise, fromyits rest position, shown in Figure 4, acts against a restraining forcewhich is applied to the upper surface'143 of generally L-shape link 134.This force is provided by an assembly 144 supported at the exterior ofpanel 12, which comprises a hollow cylinder 145, a plunger` 146extending from the bottom end of cylinder and an adjusting screw 147which works upon a cornpression spring (not shown) within cylinder 145which spring-loads plunger 146. Assembly 144 provides a force which issuicient to restore joggle lever 3 toits rest position when the latteris released, thereby simultaneously restoring the joggling machine toits neutral position.

The extent of rotative or angular movement of joggle lever 3 iscontrollable to the end that the depth of joggle in aY work piece may becontrolled. This rotativeV or angular movement of'joggle 1ever3 may bemaintained within prescribed limits b'y means of a pair of adjustablestops 148 and 149 suitably mounted on a slide bar 151which'isaflxedthroughY bolts 152 and a spacer block (not shown) to theexterior surface of'plate 12. As shown in Figure 4 the stops 148 andr149andthe slide bar 151' are so locatedrelative to the joggle lever 3 thatthe central portion of joggle lever 3 lies within the space betweenstops 148 and 149 and the opposite lateral edges of ijogglelever 3 areengageable therewith. Stops'148 and. 149 are of a shape to permit themto be fitted upon slide bar 151 and may bemoved toward or away fromeach. other on bar 151 and aixed indesired. positions through usualfasteningmeans to dene the limits of movement of joggle lever 3. Theupper stop 143 will. be positioned at apoint on bar, 151 which will haltjoggle lever 3 at itsrrest position. and movable assembly 2 inV itsneutral position'.`

To'support awork-pieceA inclampedV position for the joggling operation)there are` provided apair of jawholders; 153 and 154 which are aixed'to,the workingsurfaee 31 of tableplate26fofrnovableassembly 2 and asecondpair of tjawholders 155 and 156 supportedupon `workingvsurface'22'of table plate 14ofpedestal 1.

Each of. the forward jawholders 153 and 155 has' the undersideof `its body member 157 milled to afford av T-slot 158 whereby the bodymembers 157 may be fitted ,t to T-shape slide runners 159 which aresuitably aixed.

movements of the movable jawholders 153 and 155 toward' l and away fromrear or stationary jawholders 154 and156.

it is obvious that with this construction there can bey no verticalorside-to-side movements of the movable jawholders 153 and 155.

Each pair of jawholders 153-154 and 155- 156 mount a pair of cooperatingjaw members 162y and 163. Each jaw comprises a body member 164k having'adovetail portion 165, by means of which it may be clamped to aijawholderas will be described. Opposed faces 166 and 167 of the jaw members 162and 163 are provided configura tions to conform to the shape of thework-piece to be joggled. In Figure l the typical work-piece A selected,by way `of example, isof generally Z -shape in cross section and itsvertical llanges a1 and web portion a2 are supported withinappropriately shaped slots or grooves provided in the mating faces 166and 167 of the jaws 162 and 163. lt is understood, of course, that thepresent inventionl is not restricted to use only with Z-shapeworkpieces. It is readily apparent that jaws 162 and 163 can be providedwith mating faces 166 and 167 of various configurations to conform toand permit use with-work pieces of various cross-sectionaleonformations.

hfiovaole jay/holders and 155 are alike in construction and assembly andthe structural details of but one will therefore be described, and thatone will be assumed to be ,iawholdcr 153 and will be described inconnection with Figure 6. As illustrated body member 157 has its forwardface 16S cut-away to provide a-slotl dependent portion 177 at itsprojected end. The projected end of plate 176 with its dependent portion177 cooperates with slot 169 to effect a cai/ity which is of generallyvdovetail outline for the accommodation of the dovet'aill portion of ajaw member 162. lt is noted that clamping plate 176 is mounted formovement relative to 'body member 157. An inwardly tapered opening 178extends from the top surface 179 of clamping plate 176 t0 the undersurface 131 thereof. A tightening knob 182 carrying a threaded member134 is positioned upon clamping plate 176 at opening 178, the threadedmember 184 passing through opening 17S and being threaded into a tappedhole in the body member 157. A washer 186 `spans thev entrance totapered opening 17S and the bottom sur face 187 ol' knob 182 bearsthereagainst. Rotation of knob 182 to move threaded member 134 intotapped hole 185 forces clamping plate 176 downwardly toward body member157 to mesh dependent portion 177 of the plate 176 with thel dovetailportion 165 of the jaw member to bel accommodated. This movement of'dependent portion 177 of plate 176 into mesh with the dovetailportionvent dovetail portionl 165 from being slid'endwise-out ofmountedposition-on body member 157.

grasses 9 The tightening force to rigidly maintain a jaw member in placeis applied to clamping plate 176' and therethrough to the jaw memberwhich is to be mounted by a pressure assembly indicated generally at180. Pressure assembly 180 comprises a cylindrical shaft 188 having aneccentric portion 189 and a reduced portion `191'. Cylindrical shaft 188is of sutcient length to span the width of body member 157 and projectto either side thereof, and is supported for rotative movement withinaligned openings 192 providedin spaced wall portions 172 and 173 of bodymember 157. A through hole190 is provided at one projecting end 193 ofshaft 188 to accommodate a turning lever 194 by means of which rotativemovement of shaft 188 maybe attained. A screw 195 is threaded `throughshaft 188 adjacent its opposite end at the reduced portion 191. Screw195 and lever 194 act to prevent shaft 188 from moving endwise out ofoperative position on body member 157. Positioned at the eccentricportion 189 of shaft 188 is a pin 196 having a head 197 whiclirides uponeccentric portion 189 and a shank 198 which extends upwardly into anaperture in plate 176. An annular shoulder'201 is afforded on head 197which is adapted to press against the under surface 181 of clampingplate 176. ln the final tightening of clamping plate 176 upon a dovetailportion 165 of a` jaw member, lever` 194 is depressed downwardly torotate shaft 188 and` revolve eccentric portion 189 as in a cam actionto force headv 197 of pin 196 against the under surface 181 of clampingplate 176 to ypivot plate 176v in a counterclockwise direction aboutthreaded member 184 to secure clamping plate 176 firmly upon thedovetail portion 165 of the particular jaw member being mounted. Thusknob 182 and itslass'ociated threaded member 184 are not required toeffect the rigid clamping of the jaw member tothe jawholder b ut ratherserve to so move clamping plate176 that thelatter will cooperate withthe dovetail portion 165 of a jaw member to slidably hold the jaw memberupon the jawholder. The tightening or securing'force to aix the jawmember to the jawholder is derived from the cooperation of shaft 188 andpressure pin 196.

There has been described the means for clamping jaw member 162 tomovable jawholder 153. The second movable jawholder 154 and theoppositely faced stationary jawholders 155 and 156 which cooperate withmovable jawholders 153`and`154` maintain their jaw members 162 and 163in the same manner as does jawholder 153. Thus each of the jawholders154, 155 and 156 embodies a clamping plate176, an adjusting knob 182with its asso-'1 ciated threaded member 184, a pressure shaft `188 withits eccentric portion 189, a lever 194 to actuate pressure shaft 188,and a pressure pin 196 havinga head 197 adapted to act upon theundersurface of the clamping plate 176 to cause the latter to be clampedfirmly upon the dovetail portion 165 of a jawholder.

Since the various jaw lmembers 162 and 163 are adapted by reason of themounting arrangement described to be slidablyendwise movable withintheir respective jawholders, it is obvious that thewidth of joggle of aworkpiece is set by adjusting the lateral spacingbetween the jaw pair162-163 `carried by jawholders 153-154 onv table plate 26 of movableassembly 2 andthe jaw pair 162-163 carried by jawholders 155-156 ontable plate 14.0f pedestal 1, before the clamping plates 176 of "thevarious jawholders are rigidly clamped upon the dovetail portions 165`ofthe'yarious jaw members. To accommodate the jaw membersl 162 and 163carred by the various jawholders to various thicknesses of workmaterial, movable jawholders 153 and 154` are` adapted to be movedrectilinearly upon slide runners 159. To effect this movement ofjawholders 153 and 154, there is provideda pair of actuating assemblies,indicated generally at 2 05 and 206, in operative associationhwith thesejawholders; f

, Actuatinzg assemblies" 205 and 206 are alike in construcl Cil 10 tionand purpose and as shown, eachcomprises a bracket- 207, the bracket 2,07ofv assembly 205 being suitably rigidly atlixed to the exterior surfaceof wall member 27 of movable assembly 2 and the bracket 207 of assembly206 being also suitably rigidly atiixed to the exterior surface `ofplate 11 of pedestal 1. Each bracket 207 is of generally U-shapehavingspaced triangular-shaped legs 208, with pivot apexes as at 209.Pivot apexes 209 are provided with aligned openings for rotatablysupporting a pivot pin 211. An elongated, generally block-like,adjusting bar 212 is pivotally mounted substantially cenA trally of itslength on pivot pin 211. The upper end of adjusting bar 212 is milled ontwo sides to form a lug-like extension 213 to which an end of a linkV214 is pivotally fastened by a pin 215. Spaced from the lug 213 there isprovided in adjusting bar 212 a horizontal front-to-rear threadedopening 216 which accommodates the threaded portion 217 of a screw knobmember218,

l The rear end of threaded portion 217 is adapted to bear against avertical stop element 221. Vertical stop element 221 of actuatingassembly 205 is welded to working surface 31 of table plate 26 ofmovable assembly 2 while plate221 of actuating assembly 206 is welded toworking surface 22 of table plate 14 of pedestal 1. A second screw knobmember 222 is operatively supported by the adjusting bars 212, eachadjusting bar being provided near its lower end with a horizontalfront-to-rear threaded opening 223 for accommodation of the threadedportion 224 of screw knob member 222. The outer end of threaded portion224 is adapted to engage and bear upon the bight portion of thegenerally U-shaped bracket 207. j

Links 214 which are pivotally connected at one of their ends to lugextensions 213 of adjusting bars 212 are connected at their oppositeends by a pivot pin 225 to locking levers 226. Locking levers 226, asshown, each comprises an elongated flat body member 227 having an upwardjog as at 228. The connection of links 214 to locking levers 226 is madeintermediate the ends thereof and in the area of the jog 228. Eachlocking lever 226 has a handle portion 231'atforded at one of its ends232. The opposite ends 233 are projected into the vertical slots 171 ofthe body members 157 of the movable jawholders 153 and `154 and aretherein pivotally interconnected with the spaced wall portions 172 and173 of the body members 157 by pivot pins 234 whose ends are suitablymaintained within aligned openings in spaced wall portions 172 and 173.The locking levers 226 serve to securely position the movable jawholders153 and 155 relative to the stationary jawholders 154 and 156 andprevent any rectilinear movement of the former upon their v sliderunners 159.

' To space the movable jawholders 153 and 155 and the jaw members 162that they carry properly relative to stationary jawholders 154 and 156and the jaw members 163 supported thereon to accommodate the thicknessof a work piece to be joggled, it is necessary merely to) movepivotpins`225` toward or away from the jawholders 153 and155 dependenton the direction of movement atforded bars 212 by screw knob members 218and 222 Y to effect rectilinear movement of jawholders 153 and 155 ontheir slide runners 159 toward or away from their associated stationaryjawholders 154 and 156.

In the construction hereinabove described the various jawholders 153,154, and 156 are adapted readily to assume a separated position relativeto one another to permit the placement of a workpiece, lateraldisplacement between jaw members 162 and 163 is quickly achieved todetermine the width of a joggle in the work. l piece,I the workpiece issecurely maintained in the accom? plishment of the joggle, and yremovalof the workpiece after the joggling operation is easily effected.

Inthe performance of a jogglingA operation the proper spacing betweenthe individual members of each pair of jawholders 153-154 and 155-156 toaccommodate a given workpiece thickness must be effected and jaw members 162 and 163 carried by jawholders 153-154 must be properlylaterally spaced relative to jaw members 162 and 163 of jawholders 155,156 to achieve the width of jog desired in the workpiece.

With the jawholders 153-154 and 155-156 in the open position, the twopair of jaw members 162 and' 163 are slidably mounted thereupon, onepair to each set of jawholders, and dispoed such that the faces 167 ofthe rear jaw members 163 mate with the faces 166 of the forward jawmembers 162. The lateral spacing between the jaw members 162 and 163carried by the pair of jawholders 153-154 and the jaw members 162 and163 mounted on the pair of jawholders 155-156 is then specically set byhand to define the exact width of jog desired in workpiece A. Knobs 182on each of the four jawholders are turned to actuate the clamping plates176 downwardly toward the jaw dovetails 165 to take up slack.l Levers194 of the jawholders are then pressed downwardly to rotate shaft 188and move pin 196 upwardly to apply pressure .upon clamping plates 17 6which pivots the latter upon studs 184 to cause them to rigidly clampdown upon the jaw dovetail 165.

To adjust the assembly to accommodatethe thickness of the workpiece,locking levers 226 are. pressed downward to slide movable jawholders 153and 155 along runners 159 into position adjacent stationary jawholders154 and 156. ln this movement the ends of links 214 rotate about thepivot pins 215 and 225 and levers 226 turn about holding pin 234, Thisaction results in a force being applied to the pivots 234 to effect thedesired movement. of movable jawholders 153 and 155 which carry pivots234. With movable jawholders 153 and 155 positioned adjacent stationaryjawholders 154 and 156 the screw knobs 218 and 222 are manipulated toadjust the position of adjusting bar 212 until the spacing between themating faces 166 and 167 of jaw members 162 and 163 is the amountrequired by the thickness of the workpiece. Adjusting bars 212 in thisoperation are caused to .pivot about pins 211, translating a horizontalmotion through .pins 215, links 214, pins 225, locking levers 226, andpins 234 to jawholders 153 and 154-forward or rearward-depending on thedirection of turning of vknobs 213 .and 222.

After the various jawholders and their associated jaw members have .beenproperly adjusted and Vlocated relative to one another the lockinglevers 226 are raised to separate the movable jawholders 153 and.,155from stationary jawholders `154 and 156. WorkpieceA isplaced in.position on the jaw members 162 of the movablejawholders .153 and 154and locking levers `22,6 are then pressed down to actuate jawholders 153and 155 to their closed l positions thereby locking workpiece A in.position.

The depth of joggle is then set by adjusting and setting lower ,stop 149on slide bar 151, the position of stop 1.49 determining the vextent ofdownward movement of joggle lever 3 and thus the extent of joggle depth.

Now with workpiece A locked in position the machine isset to effect thejoggle. Forsake of illustration it is assumed that a joggle is requiredwhich will shape the workpiece A so that it appears as shown in Figurela. To effect this joggle, it is necessary to index the present machinesuch that movable assembly 2 willmove rearwardly, or to the left asviewed in Figure 1, when joggle lever 3 is .depressed downward to thedotted line position illustrated in Figure l. Such indexing isaccomplished bylrotating'thetcontrol wheel4'until indicia 4a pointsrearward. To secure lthe desired rotation of control wheel 4, a forcefis yapplied to the handle bars 82' of wheel 4 to -move it normal tocover plate 28. Thismovement is accomplished against the load spring S9and serves to disengage pin 94 from camming wheel 11 and to vwithdraw itfrom whichever of the circular openings 101, 102 or 104 in plate 24 thatit may have been occupying. With pin 94 held in this withdrawn positionwheel 4 is rotated until indicia 4a points rearward. At this setting, onrelease of wheel 4, pin 94 is in position to be projected, under theforce of spring 89, into and through circular opening 103 in plate 24and into slot 115 of camming wheel 111. The rotation of wheel 4, whilepin 94 is in its withdrawn position, will result in like rotation ofdrive Sprocket 92 through the agency of pin 94; movement of drivesprocket 92 will actuate the chain drive 107 to rotate the varioussupport assemblies 35 an amount Sullicient to properly locate the bodymembers 44 thereof so that the slots 46 therein lie parallel to theupper andl lower edges of plate 24. The support blocks 45 of theassemblies 35 which rest in slots 46 will then confine. they assemblies35, and hence movable assembly 2, to movement in a horizontaldirection-forward or rearward from neutral-as hereinbefore described.

Now with pin 94 resting in slot 115 of camming .wheel 1'11 and slots 56properly located, joggle lever 3 is pressed downward. This causesmovement of links 134 and 135 to effect rotation of shaft 118. Cammingwheel 111 connected to the inner end of shaft 11S will rotate in unisontherewith and in a clockwise direction as viewed from the control wheelside of the assembly 1. Pin 94 whose end 105 projects into slot 115 ofcamming wheelv111 will have pressure exerted against its sides to bodilymove the tpin 94 rearwardly. As pin 94 is secured to plate 24 of movableassembly 2 through control wheel 4 and bolt 87, plate 24 will shifthorizontally rearwardly sliding upon support blocks 45 and movableassembly 2, of which plate 24 is a part, will be displaced to the rearshifting the pair of jawholders 153-154 relative to the pair ofjawholders 155-156 to produce the type of joggle in workpiece A as shownin Figure 1a. Locking levers 226 are then operated to withdraw movablejawholders 153 and 155 from stationary jawholders 154 and 156 to permitthe formed workpiece A to be removed.

It is noted that as joggle lever 3 is depressed. from its rest position,it encounters a restoring force in vthe assembly 144 whose spring-loadedplunger 146 contacts surface 143 of link 1.34. Thus when the jogglingoperationis complete and the workpiece A removed joggle lever 3 isreleased, the force of plunger 146 will react to return joggle lever 3to its neutral position as determined by stop 148 on slide bar 151, andto carry movableassembly 2 back to its neutral position.

If it were desired to produce a joggle opposite to that described, amotion of the movable assembly 2 forward, or to the right as viewed inFigure l, is required. In this case, control wheel 4 is manipulated toposition indicia 4a pointing to the front of the machine. Pin 94 willhave been moved, in the manipulation of control wheel 4, to projectthrough opening 101 in plate 104 and rest in the upper slot 113 ofcamming wheel 111, and the chain drive 107 will have actuated thevarious support assemblies 35 to so position the slots 56 and thesupport blocks 45 that the assemblies 35, and therefore movable assembly2, can move only in a horizontal direction from the `neutral position.Depression of joggle lever 3 imparts the same clockwise motion to shaft118 and camming wheel 111, as in the joggling operation above described.Now,

however, since pin 94 rests within upper slot 113 of camming wheel 1'11,this clockwise motion will cause pin 94, hence, movable assembly 2, tobe shifted bodily toward the right, or the front of the machine.

To produce a vertical upward joggle, it will be necessary to shiftmovable assembly 2 upwardly. In this case, 'control wheel 4 ismanipulated and actuated to direct indicia 4a upwardly. This operationof control wheel 4 will withdraw pin '94 from whichever circular openingin plate 24 it may have been occupying and will project it throughcircular opening 102 to dispose its end 105 within slot 114 of cammingwheel111. Chain drive 107 will actuate support assemblies 35 to positionslots 56v and support blocks 45 so that they would allow supportassemblies 35 and movable assembly 2 to move only in a .verticaldirection from neutral. Again, depression of joggle lever 3 results in aclockwise motion being provided shaft 118 and camming wheel 111, but nowwith pin 94 disposed in the left slot 114 of camming wheel 111 rotationof the latter will cause an upward force to be applied to pin 94 to movemovable assembly 2 upwardly and effect a vertical upward joggle.

In producing a vertical downward joggle in a work-k piece movableassembly 2 is required to move downwardly. Control wheel 4 is thereforeactuated to bring indicia 4a to a downwardly pointing position. Pin 94will now project through circular opening 104 in plate 24 and willengage slot 116 of Camming wheel 111. Chain drive 107 will have actuatedthe `support assemblies 35 to dispose slots 56 and support blocks 45 inpositions which will allow support assemblies 35 and movable assembly 2to move vertically only from neutral. Depression of joggle lever 3rotates shaft 118 and Camming wheel 111 clockwise, as in the otheroperations described. Pinl 94 will be shifted downwardly to carrymovable assembly 2 downwardly andthe downward joggle is produced.

Downward movement of movable assembly 2 is accomplished against theretarding force of spring-loaded cylinf` de r 63`which will return themovable assembly 2 to the neutral position against the force of gravityon completion of the joggling operation and removal of the joggledworkpiece.

It is evident from the above description of operation that the presentjoggling machine can be employed to effect joggles ina given congurationworkpiece in a rapid manner. Where joggles are required in differentdirections, the control wheel 4 is readily manipulatable to set thevarious directing elements as required.

It is noted that in the movements of pin 94 and movable assembly 2 inthe various directions from neutral that each movement is accomplishedthrough effecting,sby`v means of joggle lever 3, a clockwise movement ofshaft 118 andcamming lever 111. Camming lever 111 is thus;v alwaysrotated in the same direction, the change in direction of movement ofmovable assembly 2 being accom-l plished by changing the cooperation ofpin 94 with vthe peripheral slots 113, 114, 115 and 116 of Camming'lever 111. o o a Y While'a certain preferred embodiment of the inventionhas been specically disclosed, itis understood that the invention is notlimited thereto as many variations will be readily apparent to thoseskilled in the art andthe invention is to be given its broadest possibleAinterpretation within the terms of the following claims.
